Some may find this little update interesting:

This afternoon (ambient 28deg C at time of test) could not control myself and needed to go for a drive during the week I simply adjusted the plug gap, changed the spacing of the leading plugs distance from the rotor face, took 2% out of my main ECU fuel table and turned my W/M back to 3 turns setting.

Drive it and its an animal :shock: pulled the best yet and I was game enough to look at the mixture meter before hitting 7800rpm in 3rd gear (100mph or so) and it was 10.5 to 10.6:1 AFR the power on the on board logger showed 415rwhp (est 498bhp). I was expecting the AFR to go leaner as last time I tested it in that spec on the water injection setting it was about 10.9:1 AFR (but I changed the plug gap *narrower*) and took a tiny bit of fuel out of the ECU map? and it went the other way?).

It was allot of fun
and I hope also to get back one input box from Race Logic (sent for repair!) then I can hook up all the proper instruments and do some more tests, relative to the first one. My intention was to reduce the fuel mixture to somewhere around 11.8:1, but it feels very great as it is now + set like this is less stress full on the engine and turbo especially when pushing high gears and speeds for extended power use............. thoughts anyone?

Oh here is a pic of the WI testing (not sure if I posted this in other pages, I'd reload to check but I have the gayest internet speed in human existence)
